She's also become a vocal advocate for mental health and sexual assault, speaking candidly about her battle with endometriosis and delivering a rousing, widely praised speech at the 2018 Women's March in New York City.

Last year, she opened up about being biracial and her struggle to navigate two disparate identities.

“I look like a white girl, but I don’t feel like one. I’m a black woman. So it’s been weird navigating that," she toldPlayboy. "When I was growing up I didn’t know if I was supposed to love TLC or Britney."

Halsey is currently on the road in Australia for the final leg of her Hopeless Fountain Kingdom tour, which wraps September 26 following stops across Europe, Latin America, Asia, Canada, and the U.S. She also plays a small part in Bradley Cooper's Lady Gaga-fronted A Star Is Born, slated for release October 5.
